基于IFC的水利水电工程信息模型存储标准研究

Research on storage standard of water projects information model based on IFC

为规范水利水电工程信息模型(WPIM)数据在全生命期各阶段的存储和交换,基于国际标准Industry Foundation Classes(IFC 4.0.2.1)规定的数据模式,研究了水利水电工程信息模型的数据存储标准。结果表明:在IFC标准规定的领域层、共享层与核心层中新增水利水电工程空间结构单元(Spatial Structure Element)、构件单元(Element)两类实体和相关关系实体,通过新定义实体(Entity)、预定义类型(Predefined Type)、属性集(Property Set)的方式,扩展编制了水利水电工程信息模型存储标准。该标准是中国水利水电勘测设计协会水利水电BIM联盟先行启动的4项BIM标准之一,适用于水利水电工程全生命期全专业的BIM模型的存储和交换。

In order to standardize the storage and exchange of water projects information model(WPIM)data in the whole life cycle,the data storage standard of WPIM was studied and extended based on the data pattern specified by the international standard industry foundation classes(IFC 4.0.2.1).We extended two kinds entities,the“Spatial Structure Element”and“Element”,as well as relationship entities in the domain layer,shared layer and core layer specified by IFC.By newly defining entities,predefined types and property sets,we extended the storage standard of WPIM.The proposed standard is one of the four BIM standards launched in pilot by The BIM Union of China Water Conservancy and Hydropower,which is suitable for the storage and exchange of WPIM for all specialties of water projects in the whole life cycle.
